Question

In MySQL, is there a way in a simple SELECT to obtain a sequence of ASCII code/code points for each character in a varchar value? I’m more familiar with Oracle, which has the DUMP function that can be used for this.

For example, select some_function('abcd') would return something like 96,97,98,99?

Answer 1

This is about the closest equivalent I’m aware of in MySQL:

mysql> select hex('abcd');
+-------------+
| hex('abcd') |
+-------------+
| 61626364    |
+-------------+
1 row in set (0.00 sec)
